   👑 FANTASTIC VISION LAB: AXP Socrates 視覺空間 — style.css (V1.0 Dual-Engine Release)
   🕒 最後優化日期與時間 (Last Optimized Timestamp)：2026-10-22 20:01 CST
   核心戰略與瑞士無塵光學實驗室升級重點 (V1.0 實體鍵盤 × 觸控螢幕雙棲元年初版)：
   1. [凡特錫色盤 100% 純化] 徹底拔除舊版殘留之 16 處刺眼螢光青 (#38bdf8) 與森林綠 (#10b981 / #0d9488 / #34d399)，全面換裝凡特錫藍 (#1E75BB / #2988D6 / #7CC2F5)・皇家深海藍 (#1A365D) 與皇家香檳金 (#B88E28 / #D4AF37)。
   2. [V1.0 鍵盤／觸控雙棲介面] 新增面板頂部「實體鍵盤 ／ 觸控螢幕」雙模切換器 (.input-mode-switcher)・舞台右上角懸浮快捷艙 (.arena-top-right-dock) 與右下角「消光暗室級虛擬十字方向舵 (.touch-dpad-container)」。
   3. [零重疊響應式幾何佈局] 當開啟觸控模式時，自動協調底部導引膠囊 (#socratic-insight-bar) 與右下角虛擬方向舵之空間配置，確保於 iPad 平板與 43"~55" 大螢幕 100% 零遮擋。
   4. [無邊框圓形消光暗室 #socrates-aperture-mask] 消除螢幕直角邊框暗示，全介面鎖定 tabular-nums 等寬防抖動與 100% 零頓號・零反引號。
